Nonsense, it Deng decision to open up China and embrace capitalism. There are of cos credit for Mao uniting the whole mainland China. Actually, it is good that Mao takeover the role of Zhu De and not involved in civil administration of PRC. He is not good in that area but a brilliant military leader. After lin biao, I will rank Mao military genuis second.It's not Deng's open up policy. It's Mao's decision. Deng's job is keep doing it and execution.
Deng need to be given full credit for economy success of modern China. He is just like Mao, very decisive. Nobody can imagine what China can achieved now when in 1978 but he has the vision. The very strange thing is China can progress even the first 20 years of China economy reform despite being having a lot of corruption.
